SELF-ADJUSTING BALL-BEARING.

Specification of Letters Patent.

Application filed November 14, 1903. Serial No. 462,657BEISSUED Patented Jam? 1911.

To all whom it may concern:

Be it known that I, SVENGUSTAF WING- onrs'r, a subject of the King of Sweden, and resident of Gottenborg, in the Kingdom of Sweden, have invented certain new and useful Improvements in or Relating to Self- Adjusting Ball-Bearings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to ball-bearings, especially adapted for axial'pressure, which bearings can easily be mounted. These bearings are self-adjusting, i. .e., so constructed, that an oblique position of the shaft or the moving of the same-radially has no influence at all upon the bearings.

The bearing is composed partly of an outer ring, made in one piece, partly of inner parts, consisting of one or more ballsets around the shaft, and of rings on both sides of said ball-set or ball-sets, which rings form bearin surfaces for the balls and in their turn i831 against surfaces on the outer ring, which form parts of the same sphere or substantially so. Notches, provided in the inner side of the outer ring, or the fact that parts of the inner rings. are cut away, make possible the mountin of the inner arts into the outer ring, wit out the aid 0 the usual ring shaped cover or the like, screwed into the bearing to keep theinner parts in position.

In the accompanying drawings Figure 1 is an axial section of a bearing arranged in accordance with this invention.

of the nearing but shows the inner parts turned as a whole through 90 e. into such position that they can inserted into the hearing or withdrawn from the same. Fig. 4 is a view somewhat similar to Fig. 3, but illustratinga' modified formation of the improved bearing with its ball sets omitted; Fig.5 is a view somewhat similar to Fig. 3, but illustrating another modification 6 is a vertical section taken through the form all sets being omitted; Fig. 7 is a sectional detail View somewhat similar to Fig. 1, but illustrating still another modified formation of the bearing comprised in my present invention; Fig. 8 is a detail View showing certain features of construction of the bearing illustrated in Fig. 7, and Fig. 9 is a view similar to Fig. 1,

Fig. 2 is a side view of the same. Fig. 3 is a side view but illustrating the application of the shaft to the improved bearing.

1 and 2 are twosets of balls, 3 is a ring,

located between the said sets and fixed on a the shaftin any suitable manner, 4 and 5.

are rings disposed in the same planes as the ball-sets respectively and rovided with grooves, projections or the like, embracing the balls, 6 and 7 are side rings and 8 is the outer ring.

9, 9, Fig. 1, designate parts of the frame of the bearing forming bearing surfaces for the outer ring. 1

The rings 6 and 7 support the ball-sets 1 and 2 from each side respectively longitudinally of the shaft and the outer sides of the said rings bear against the inner side of the ring 8 forming parts ofa sphere 10,

the center of which is situated on the center line of the ring 8. The pressure from the shaft is transmitted by the ball-sets either to the ring 6 or to the ring 7, and thus to the ring 8, which is prevented by the arts 9, 9 from moving longitudinally of the shaft. Owing to the spherical bearing surfaces of the ring 8 and the rings 6' and the said pressure is distributed uniformly on all the balls of the set even if the shaft and the ring 3 should not run regularly. Owing to the fact that the ring 8 has plane end surfaces and can move transversely in its own plans between the parts 9, 9, the bearing as a whole can be moved radially, in consequence whereof the shaft can occupy an oblique position to the center line of the ring 8 and at the same time, a lateral position, as shown in Fig. 9, in which the line b indicatesthe said position of the shaft 12 and the line a the ordinary position of the its inner edges, with recesses 11, 11, so

adapted that the rings,'when so placed that they form an angle of 90 with the ring- 8, ean be put into the same, Fig. 3. By inthe inner rings in the said manner seiting the same sidewise the and then moving rings can easily be mounted in the outer ring and the balls between the same, the whole being then turned into the position shown in Fi 1., v

The modification shown in Fig. 4 conperiphery v extent, that I eter of the ball track is so adapted, that outer, rin

- ner in which the track is not alfected'by parts being thus cut away.

Figs. 7 and 8 show a bearing constructedin the described manner but only one set of balls.

In addition to the self-adjusting capacity of the described bearing and the easy manthe parts be assembled, it has the great advantage that it cannot be tlghtened and consequently cannot be damaged T tightened. The adjusting is effected during the manufacturing of the bearing and no adjusting is thereafter necessary.

' now described my invention,

Havln what I c aim as new and desire to secure by provided with Letters Patent is l. A self-adjusting bearing having an a ball set, inner rings located at opposite sides of the ballset and provided with concentric sphericalsurfaces contacting upon corresponding surfaces within said outer ring, a shaft and means fortransmitting the axis pressure of theshaft to said outer ring through the balls, said ring be ng provided with a space at one v side for the introduction of the inner rings and ball set within said ring.

2. A self-adjusting bearing having two ballsets, lateral inner rings located atopposite sides of the ball sets, an outer ring inclosing said ball sets and lateral inner rings and having spherical surfaces whereon said lateral rings having corresponding surfaces are engaged, and an intermediate inner ring engaged between the respective of the bearing can by being carelessl y I l l l l i I j located at opposite provided with concentric spherical surfaces contacting upon corresponding surfaces within said outer integral ring, and uneaus for transmitting the axial pressure of the shaft to said outer ring through the balls, said integral outer ring being provided with means for the introduction of the inner rings and ball set within said outer ring.

4. A self-adjusting bearing having an integral outer ring, a ball set, inner rings located at opposite sides of the ball set and provided with concentric spherical surfaces contacting upon corresponding surfaces within said outer integral ring, and means for transmitting the. axial pressure of the shaft to said outer ring through the balls, said integral outer ring being provided with means for the introduction of the inner rings and ball set within said outer ring, when turned at approximately right-angles thereto.

A self-adjusting bearing having an integral outer ring, a ball set, inner rings sides of the ball set and provided with concentric spherical surfaces contacting upon corresponding surfaces within said outer integral ring, means for transmitting the axial pressure of the shaft tosaid outer ring through the ball set, the inner rings and the outer ring being relatively so shaped as to permit the introduction of the inner rings and ball set within said outer ring when turned at an angle thereto. y

In witness whereof, I have signed my name in the presence of scribing witnesses.
